Cozy Telegram Guestbook turns your TRMNL into an ambient messaging board. Pair it with your own Telegram bot, anyone who scans the QR can leave a note, and the five most recent messages cascade on your display. Built by Cozy Scenes.
Available settings
Bot Token
Use a dedicated Telegram bot for this plugin. Anyone who scans the QR code on your TRMNL can send a message to your display. Use it as a tiny guestbook, office message board, family note wall, event shout-out screen, shared reminder board, or a fun way for visitors to leave a quick hello.
Setup:
1. Open Telegram and message @BotFather
2. Send /newbot and follow the prompts
3. Copy the bot token and paste it here
Keep this token private — it controls your bot.
Example: 123456789:ABC-DEF1234ghIkl-zyx57W2v1u123ew11
Bot Username
The bot's @ handle without the @ symbol. Used for the QR code and the on-screen display.
Example: my_cozy_bot

Built-in QR is recommended. Custom image URL lets you use your own styled QR. Hide QR removes the QR area.
Custom QR Image URL
Optional. Only used when QR Display Mode is set to "Custom QR image URL". Use a direct image URL ending in .png, .jpg, .jpeg, or .webp.
